Hi,
the program works perfectly for transforming my java classes into XML
files when not using the mapping file. Therefore I think I have to
change the accessor methods in those classes involved in the 1:N
relation and the type of those fields in the mapping file, am I right?
Thanks in advance.

Okay, can you try things on the XML side without using a mapping file,
just for the sake of completeness ?
